They continued to collaborate after graduation, and a mutual friend (a representative of Source Records) suggested that they do a track for Sourcelab 1, the first compilation released by Source Records in September of 1995. They recorded Modular Mix, which became a hit on the United Kingdom charts.

air signs enjoy the qualities of air, the intangible things in life. they are stimulated by the intellectual, often forgetting the real world looking for something new to learn. air signs tend to be attracted more to ideas than to action. in reacting to the world, they tend to shove aside pratical and emotional responses, attempting to make rational, unbiased decisions. this may make them seem cold or uncaring in relationships.

AIR is email/chat-speak for as Irecall, similar in meaning and useage to IIRC ("if I remember/recall correctly"). AIR is seen less frequently, a bit more poetic, and sometimes more honest (or humble) than IIRC. IIRC implies that the statement is correct if recalled correctly: this does not acknowledge that the speaker may have been initially misinformed. AIR makes no such assertion.

Air is, of course, useful for many other things beyond breathing. It's a useful medium for the convection of heat and for burning things in. This is because of the level of oxygen content. The world would be a cold place above its surface without air.

We get many of the things we need for manufacturing from the air. The nitrogen and inert (noble) gases are quite good at stopping oxidation (burning) during welding, and of course, the oxygen is useful if we need to burn something. The Argon that we can seperate from the air is used in light bulbs to prevent the burning of the filament, and liquid nitrogen is quite useful for freezing things. Beyond that, air allows soundwaves to travel through the space around us into our ears, and so allows us to communicate verbally. Air can be used to inflate things that we need to be large when used, but tightly packed for travel, and the comfortable ride in cars due to the pressurised tyres comes courtesy of the air.

So there it is - air. Unless you're in space, it's likely you're surrounded by it.

Air is the substance that surrounds us, and which we breathe. I have been recently surprised at how little people actually know about air (like people in The Weakest Link, a quiz show, not knowing what percentage of air is oxygen). So I will ouline the basics of what is known as air.

Location

Air occurs in the atmosphere. In fact, the atmosphere is defined as the area around the planet that contains gases. For more on the atmosphere, you can go here.

Composition

The air is made up primarily of gases. It is almost entirely a mixture of nitrogen and oxygen, but contains other gases too, and also suspended dust and small organisms such as bacteria. The percentage of gases (and other stuff) in the air varies with altitude, location and humidity, and also on the particular time, as wind, for example, plays a part in determining the air's composition. Water vapor is the gas which varies most. In desert areas, water vapor may account for as little as 0.1% of the air, while in warm, humid zones, it may be as much as 6%. The higher up we go, the less heavier particles are found in the air, so the higher we go, the percentage of lighter gases goes up, and there is very little dust and particles. A typical composition of dry air is shown below.

The molecular level

Air molecules take up only 0.1% of the volume they occupy.
Thus 99.9% of air is actually a vacuum. There are 2.7 x 1019 molecules in every cubic centimeter of air, and the average speed of air molecules is about 500 m/s. Because of this, air molecules are constantly colliding with each other. Each molecule has about 5 collision every nanosecond!

Uses

The greatest commercial use for air is in obtaining the separate gases from it. The major gases (nitrogen, oxygen and the noble gases)
are extracted using fractional distillation. Before this, water vapor and carbon dioxide are removed, as they freeze at low temperatures (other gases liquify), and the solids would block the equipment.

Also produced by distillation are noble gases, most notably argon, which provides an inert atmosphere in metallurgy, as is used in neon lights. (Neon lights are not always made from neon. In fact, any gas which emits light when a current is passed through it works. Neon, specifically, emits an orange-red light, while argon produces a blue-green light.)

Air (#), n. [OE. air, eir, F. air, L. aer, fr. Gr. , air, mist, for , fr. root to blow, breathe, probably akin to E. wind. In sense 10 the French has taking a meaning fr. It. aria atmosphere, air, fr. the same Latin word; and in senses 11, 12, 13 the French meaning is either fr. L. aria, or due to confusion with F. aire, in an older sense of origin, descent. Cf. Ary, Debonair, Malaria, Wind.]

1.

The fluid which we breathe, and which surrounds the earth; the atmosphere. It is invisible, inodorous, insipid, transparent, compressible, elastic, and ponderable.

⇒ By the ancient philosophers, air was regarded as an element; but modern science has shown that it is essentially a mixture of oxygen and nitrogen, with a small amount of carbon dioxide, the average proportions being, by volume: oxygen, 20.96 per cent.; nitrogen, 79.00 per cent.; carbon dioxide, 0.04 per cent. These proportions are subject to a very slight variability. Air also always contains some vapor of water.

2.

Symbolically: Something unsubstantial, light, or volatile.

"Charm ache with air."

Shak.

He was still all air and fire. Macaulay

. [Air and fire being the finer and quicker elements as opposed to earth and water.]

3.

A particular state of the atmosphere, as respects heat, cold, moisture, etc., or as affecting the sensations; as, a smoky air, a damp air, the morning air, etc.

A musical idea, or motive, rhythmically developed in consecutive single tones, so as to form a symmetrical and balanced whole, which may be sung by a single voice to the stanzas of a hymn or song, or even to plain prose, or played upon an instrument; a melody; a tune; an aria.

(b)

In harmonized chorals, psalmody, part songs, etc., the part which bears the tune or melody -- in modern harmony usually the upper part -- is sometimes called the air.

11.

The peculiar look, appearance, and bearing of a person; mien; demeanor; as, the air of a youth; a heavy air; a lofty air.

"His very air."

Shak.

12.

Peculiar appearance; apparent character; semblance; manner; style.

It was communicated with the air of a secret.
Pope.

12. pl.

An artificial or affected manner; show of pride or vanity; haughtiness; as, it is said of a person, he puts on airs.

The representation or reproduction of the effect of the atmospheric medium through which every object in nature is viewed.

Carriage; attitude; action; movement; as, the head of that portrait has a good air.
